Abstract
Three plants (Gnidia glauca (Fresen.) Gilg, Lygodium
japonicum (Thunb.) Sw. and Ocimum basilicum L.) were selected
in order to investigate presence of various phytoconstituents. Plant leaves
from three plants were collected, dried and extracted in Acetone, chloroform,
methanol and water. Preliminary phytochemical analysis (qualitative) and total
phenol, tannin, total alkaloid contents were carried out using
spectrophotometric method. Antifeedant activity was evaluated against
lepidopteran pest (Spodoptera litura Fab.) using a no-choice disc
method. Methanolic extract of G. glauca recorded the highest tannin
content (0.634±0.046 mg TAE/g DW) followed by methanolic extracts of O.
basilicum (0.576±0.002 mg TAE/g DW). Methanolic extract of L. japonicum
recorded the highest phenolic contents (0.826±0.034 mg CE/g DW). The G.
glauca leaf extract (5%) in methanol exhibited highest antifeedant activity
(52.56±0.003%) followed by 5% acetone extract (38.76±0.57%).
